“A pioneering genetically modified (GM) wheat crop that emits an insect alarm pheromone to ward off pests has not worked in field trials. … Compared to a control crop of wheat, the GM crops showed no improved yields, no reduction in aphids and no increase in attacks by aphid predators (such as parasitic wasps and ladybirds). … Making the site secure added around £1.8 million (US$2.8 million) to the study’s research cost of £732,000.” (http://www.nature.com/news/gm-wheat-that-emits-pest-alarm-signals-fails-in-field-trials-1.17854)

Humans appear to be the only alarming pests here.

“‘Double-muscled’ pigs are made by disrupting, or editing, a single gene … and … the breed could be among the first genetically engineered animals to be approved for human consumption. … The pigs provide many of the double-muscled cow’s benefits — such as leaner meat and a higher yield of meat per animal. However, they also share some of its problems. Birthing difficulties result from the piglets’ large size, for instance. And only 13 of the 32 lived to 8 months old.” (http://www.nature.com/news/super-muscly-pigs-created-by-small-genetic-tweak-1.17874)

And here too the humans rather than the pigs seem to be the sentient monsters.

“In rich Western nations, preaching about how eating a lot of meat is bad for both one’s health and the planet provokes resentment. Meanwhile, in developing nations, the rising middle-classes can at last afford to eat more meat, which was previously a luxury. It’s not surprising that governments worldwide duck out of tackling the problem.” (http://positivenews.org.uk/2015/environment/agriculture/17608/eating-meat-save-planet/)

How about tackling the duck?

“Nitrous oxide is found in manure and fertilisers, whereas the methane emissions come from burping cattle and sheep.”

Have to burp ’em, else they swell up and float away. That’s not clouds; that’s methane-high sheep.
